Tested by in turn calling findComponent() from findSubComponent() it does not work as expected since the recursive logic to find the component differs for both methods.

Replacing findSubComponent() as below with the latest changes does not work. To verify run javax/swing/JColorChooser/Test7194184.java by replacing the findSubComponent() as below.


    public static Component findSubComponent(Component parent, String className) {
        String parentClassName = parent.getClass().getName();

        if (parentClassName.contains(className)) {
            return parent;
        }
        return findComponent((Container) parent,
                                 c -> parent.getClass().getName().contains(className));
    }
